I think ... This <Fn+Fxx> keys controled by SPIC(Sony Programmable I/O Control Device).
Download a picturebook application from
http://samba.org/picturebook/
and make it.
and check with this command...
# capture -j
then press <Fn+Fxx> keys. May be you can see the press event...
Here is a event data...
<Fn+ESC> : event 0x10 0x29 & event 0x10 0x28
<Fn+F1> : event 0x11 ------ same -----
<Fn+F2> : 0x12
: : <F3> -> <F11> : 0x13 -> 0x1b
<Fn+F12> : 0x1c
<Fn+"1"> : 0x21
<Fn+"2"> : 0x22
<Fn+"B"> : 0x35
<Fn+"F"> : 0x33
<Fn+"E"> : 0x32
<Fn+"S"> : 0x34
<Fn+"D"> : 0x31

Recompile the your Kernel with "Enable console blanking using APM" option.
then the backlights off.(only text console)
I checked Kernel 2.2.17,2.2.18 & 2.4.2

My VAIO could(can) go into suspend mode....but never wakeup.

addition....
You can use the internal USB-Memory-Stick device with Kernel 2.2.18 and usb-storage module. and the sound module is ymfpci.
take care about ymfpci module... because, some time I get a NOISE!!!
in this case just shutdown(not reboot!).

Thanks
